In a preferred embodiment, the coil pocket has a length of about 115 mm, a width of about 100 mm, and a radius of the bottom arc of about 60 mm.
The host fixing section 2 is generally designed in a shape to be compatible with the charger host 201 of the external charging apparatus. In a preferred embodiment, the host holder 2 is configured as a substantially rectangular host pocket with a rounded bottom. The front side of the host pocket is composed of sandwich mesh cloth 7b, so that the host pocket is comfortable and breathable; an elastic band 8b is arranged at the front bag opening and is used for hooping the bag opening to prevent the charger host 201 from falling out; the back of the host pocket is connected with the material used by the transition belt 4b into a whole. In a preferred embodiment, the host pocket has a length of about 130 mm, a width of about 100 mm, and a radius of the bottom arc of about 120 mm.
The connecting belt 3, the transition belt 4a and the transition belt 4b are made of breathable cotton cloth 11a, and are soft and comfortable. In a preferred embodiment, the anti-slip zones 6a,6b,6c provided on the back of the connecting band 3 and/or the transition band 4a and the transition band 4b are an array of anti-slip glue. The width of the connecting band 3 is between 20 mm and 80 mm, the length is between 500 mm and 1000 mm, the width of the transition band 4a and the transition band 4b is larger than the width of the connecting band 3, smaller than the width of the coil fixing part 1 and/or the host fixing part 2, and the length is between 40 mm and 100 mm. In a preferred embodiment, the length of the interface tape 3 is about 510 mm, the width is about 62 mm, the length of the transition tape 4a is about 52 mm, and the length of the transition tape 4b is about 42 mm. In a variant embodiment, the connecting band 3 may also be provided with a length adjustment mechanism, such as a buckle, which allows the length of the connecting band to be adjusted to the size of the user.
The overall length of the simple charging harness 300 is set to a length corresponding to the implanted medical equipment at the subcutaneous position of the chest, and the overall length is 600 mm-1200 mm. In a preferred embodiment, the overall length of the simple charging harness 300 is about 849 mm.
Although the implantation position of the implantable medical device is a subcutaneous chest position in the present embodiment, it can be understood by those skilled in the art that the technical solution related to the present invention is not limited thereto, and the simple charging harness of the present invention can also be applied to implantable medical devices at any position under the abdomen and waist when the patient is in a stable sitting posture.
In a preferred embodiment, the simple charging harness 300 has a cover 10a around the periphery thereof for reinforcing the simple charging harness.
As shown in fig. 9, the simple charging harness coil pocket is placed at the chest position in the use state, and is basically in a state where the opening is upward, the arc-shaped side is downward, and the single-layer mesh fabric faces the human body. Such that the charging coil 202 outside the body can be easily inserted into the coil pocket. As shown in fig. 10, the host pocket in the use state is substantially in a state where the opening is upward and the arc edge is downward, so that the charger host 201 is inserted into the host pocket. The cable 203 between the charger main unit 201 and the charging coil 202 is typically placed along the connection band when in use. Also optionally, at least a portion of the cable 203 may be threaded from within the connection strap to provide for proper securement of the cable 203. In a preferred embodiment, the charging simple strap 300 is provided with a cable fixing member attached to the connection belt 3 and used for fixing a redundant cable with a fixed length, such as a velcro.
In a preferred embodiment, the connecting strip 3 is further provided with a harness pad 5, as shown in figures 6-8. The back strap pad 5 is composed of breathable cotton cloth 11b, is soft and comfortable, and is connected with the front side and the back side through wrapping edges 10 b. As shown in fig. 11 to 12, the back strap pad 5 is detachable and covered on the connection strap 3 by nylon fasteners 12a and 12 b. The inner side of the back belt cushion 5 is provided with an anti-skid area 6d with the friction coefficient of the cotton cloth being more than 0.2. The strap pad 5 is a U-shaped pad after being wrapped and is placed on the neck of the patient to increase the comfort when the patient wears the strap for charging. In addition, the harness pad 5 may be wrapped along with the redundant cable 203 to reduce the inconvenience of the redundant cable.
The simple charging harness 300 can arrange the external charging coil 202 of the implantable medical device on the left or right chest of the patient without being held by hand. When the simple charging harness 300 is worn and used, the coil fixing part 1 with the charging coil 202 is placed at a position corresponding to the patient-implanted medical device 100, and the main unit fixing part 2 with the charger main unit 201 is placed on the other side of the body around the neck via the connecting band 3. The chest of the person has an angle of inclination to the vertical that helps the coil pocket containing the coil 202 fit in position to align with the patient stimulator 100 in both normal sitting and standing positions. Since the strap 300 has a certain friction force with the clothes due to gravity, the friction force between the strap 300 and the clothes can be increased by the anti-slip region 6a provided in the connecting belt 3. In addition, because the weight of the charging coil 202 is close to that of the charger main unit 201, the weight of the two ends of the strap and the static friction force borne by the strap can reach a certain balance, and the coil 202 can be stabilized at a required height position. Likewise, in the case of using the back-strap pad 5, the anti-slip region 6c on the connection band 3 interacts with the back-strap pad 5 to prevent displacement between the back-strap pad 5 and the connection band 3; the anti-slip region 6d on the harness pad 5 interacts with clothing or skin to prevent displacement between the harness 300 and the patient. Furthermore, the anti-slip regions 6a and 6b disposed on the transition zone 4a and the transition zone 4b can prevent the position of the coil 202 from being relatively displaced after the patient slightly adjusts the posture, thereby facilitating the patient to slightly adjust the posture and relieving fatigue.
As shown in fig. 13, in a modified embodiment, the simple harness for charging may be used by being worn on the left shoulder or the right shoulder.
